Application Bled June 16, 1884. (No model.)

To all whom it may concern,.- Y

Be it known that vI, OLIVER l?. FENCE, a citizen of the United States, and a resident of Des Moines, in the county of Polk and State of Iowa, haveinvented an Improved Hydrant, of which the following is a specilication.

My object is to simplify the construction, reduce the cost, and improve the operation of that class of hydrants that have a vertical sliding valve.

My invention consists in the lconstruction and combination ofa bent and hinged fulcrum, a lever-handle, a standpipe and delivery-spout, a case, a detachable case-section and valvecham ber, a detachable valve-seat, a detachable sliding valve, and an automatic check-valve, as hereinafter fully set forth, in such a manner that the completev hydrant, when attached to a service-pipe, can be readily operated by means of the handle and bent fulcrum, so that the sliding valve will remain stationary in an open or closed position, as desired, and lifted with the case and stand-pipe for repairs, whenever necessary without removing 'any ground or shutting oft` the supply and pressure in the service-pipe.

Figure l of the accompanying drawings is a side view, and Fig. 2 a transverse section, of the top portion of my hydrant, showing the construction of the handle and hinged fulcrum. Fig. 3 is a vertical section of the lower portion, showing the sliding-valve chamber, valve-seats, and sliding valves, combined with the case, stand-pipe and service-pipe. Fig. 4 shows the complete hydrant in position for use. Jointly considered, these igures clearly illustrate the construction, application, and operation of my complete invention.

A represents a tubular metal case, that may vary in length and diameter, as desired.

B is a detachable top and perforated cover,

through which the standp ipe extends and operates. I

C is a metal tube and stand-pipe, and C a spout attached to its top.

D is a fulcrum hinged to the top B, and bent into a semicircle at its top end.

D' is a collar 0r clip, clamped to the standpipe Gby means of a screw, D2. By relaxing the pressure of the screw D2 the clip D can be readily raised or lowered on the tube C, and

detached when the spout C is removed from the top of the tube.

F is a lever of the rst order, pivoted to the free end of the semicircular top of the hinged fulcrum D.

' Azisavalve-chamber and detachable section of the case A, but larger in diameter at its top end and contracted at its lower end. It is screw-threaded on the inside of its top end to receivea valve-seat and also the screw-threaded lower end of a case, A

G isa valve-seat, preferably made of brass. Its lower end is a right -hand screw that ts into the screw-threaded valve-chamber A2. Its top portion is of smaller diameter and angular, and adapted to be engaged by a wrench, so that it can be readily screwed in'and out of the valvechamber. A shoulder vat the end of the female screw in the valve-cha1nber, and adapted to receive a gasket, will restrict the downward movement of the valveseat G and facilitate its removal.

H is a tubular sliding valve, preferably made of brass, and adapted to move up Vand down through a longitudinal bore in the valve-seat G. It is open at the top, and has a screwthread on its outside, adaptingit to be connected with the pipe C by means ofa coupling, as shown in Fig. 3. `It is closed water-tight at its bottom end, and has a flange, H', that will close tight upon the gasket H2.

.H3 are slots about half an inch above the flange H. H4 is anl annular groove in the outside surface and at the top oi' the slots E.

`l 2 3 are perforations in the angularportion of the valve-seat G, 'which coincide with the groove H4'in the sliding valve when its flangeA H is drawn up tight against the bottom of the valve-seat. y

4 5 6 are perforations in the case A.

, J is a screw that extends through the top of the valve-chamber A2 into the lower end ofthe case A, to lockthern together. .I2 is aventon the opposite side.

K is a valve chamber that has a4 lateraly branch adapting it to be liXed to a service pipe, :A and a vertical extension `adapted to admit the I lower Contracted end, A3,.,0f the valve-chan.. ber and case section A?,` as `clearly s hownfin. Fig. 8.

K2 is a plug fitted in the lower end of the chamber K. the plug.

L is a coiled spring placed over the pin K3. M is a check-valve adapted to fit against the valve-seat in the chamber K. It has a stem of cruciforrn shape in its cross-section that projects up against the contracted lower end, A3, of the detachable valvechamber and casesection A2.

R represents a anged collar slipped over K is apn formel integral with the ease A to form a base for that portion of v be depressed by the lower end of the detachl able case, and the cheek-valve retained open, as required, to allow water to flow upward from the service-pipe. Vhen the hydrant is detached from the lower valve-chamber and service-pipe, the pressure ofthe water will lift and close the check-valve, and the spring will resume its normal position and aid in elevating and closing the valve. By turning the handle upwardas shown in Figs. l and 2, the short arm of that lever will depress the standepipe and the valve H attached to its end, as required, to allow the water to enter the standpipe through the water-way openings H3, and to ascend therein to be discharged at its top. A reverse motion of the handle lifts the standpipe and valve and shuts off the water, as required, to conne it below the sliding valve. The water remaining in the stand-pipe, after the valve is closed at its lower end,will escape through the annular groove H* of the sliding valve H and coinciding perforations or vents 1 2 3 in the valveseat G, and from thence through the perforations in the ground.

By forming the slots H3 at some elevation. above the flange H of the valve H, and making the space between thc iiange H and the groove H* of the sliding valve and the spate between the bottom of the valve-seat and the vents 1 2 3 in the same equal in length with the stroke of the short arm of the lever-handle,

case into the the waste is closed by the downward motion openings between the pistons, so that the pistons would close the waste-ports in advance of thefopening of the supply-ports and the supply-ports be closed in advance of the opening ofthe waste; but my manner of forming an open-ended screw-th readed valve-chamber and screwing a valve-seat and a casing in the with the fixed valve-seat, and then detachably connecting the lower end of the valve-chamber and complete hydrant with a service-pipe, is novel and greatly advantageous.

I claim as my inventionl. In a hydrant, the combination of a vertically-reciprocating stand-pipe, a detachable and adjustable clip having a bearing to support a pivoted lever, a lever of the first order pivoted to the adjustable clip, and a hinged fulcrum having a semicircular bend at iis top, to operate in the manner set forth, for the purposes stated.

2. The stationary hydrant-case and top A B, the moving stand-pipe C C, the hinged fulcrum D, having a semicircular bend at its top end, the clip D, and a lever-handle, F, arranged and combined as and for the pui poses shown and described.

3. A metal tubular easing having` wasteopenings at itsv lower end, a detachablel valvechamber having open Yscrew-threaded ends, a detachable valve-seat having an angulaitop and waste-vents, a sliding valve having slots or water-way openings, andan annular groove and wasteway intersecting the water way openings, and a reciprocating stand-pipe and delivery-spout, arranged and combined to operate in the manner set forth, for the purposes specified.

4.' In a hydrant, the combination of a valvechamberhaving an open screw-threaded top, a detachable valveseat having an angular and perforated top of diminished diameter, and a sliding tubular valve having one or morefwaterways near its lower closedend, and an annular groove in its outside surface intersecting the top ends of the waterways,

to operate in the manner set forth, for the purposes stated. Y

5. The combination of a valve-chamber having an open screw-threaded top end, a contracted open and screw-threaded bottom end, a detachable valveseat having a perfo- V OLIVER P. FENCE.
